GB/T 9276-1996 "Test Method for Natural Weathering Exposure of Coatings" specifies the exposure test method for coatings under natural climatic conditions, applicable for evaluating the weather resistance of various types of coatings. Coated test panels are placed in a selected natural climate exposure site, and changes in the coating's appearance are regularly observed, with defects such as loss of gloss, chalking, and cracking recorded. The testing requires instruments such as exposure racks, colorimeters, gloss meters, and magnifying glasses, providing real-world environmental data for evaluating the outdoor durability of coatings.
